Title: Formation of mold for various kind of ware
Inventor: MATSUI TOSHIO
IPC: B22C9/06
Filed: 1985-02-26
Abstract: PURPOSE:To reduce the time for molding by forming a metallic film on the surface of a prototype then pouring a molten metal therein. CONSTITUTION:The prototype 1 is first manufactured of a wooden pattern gypsum pattern, etc. Metallic powder of aluminum, brass, etc. is then coated on the surface of the prototype 1 and the metallic film 2 is formed by an electroforming and plating method. The film 2 is otherwise formed to about 0.5-1mm on the surface of the prototype 1 by a thermal spraying method. The film 2 can be laminated onto the surface of the molten metal 3 when the molten metal 3 is poured into the prototype 1 after the film 2 is formed. The solidified metal is then separated from the prototype 1 and a mold is formed. Since the film 2 is formed on the molding surface, the need for finishing the mold is eliminated. The operation is thus simplified and the time for molding is reduced.

Title: Nor type synchronizing read-only memory
Inventor: OFUJI TAKESHI
IPC: G11C17/00
Filed: 1986-02-24
Abstract: PURPOSE:To speed up the operation of a large capacity synchronizing ROM by connecting in series an N-channel transistor to the one constituting a memory cell, grounding the source of the former N-channel transistor, and connecting the gate of the same with a signal line for pre-charging. CONSTITUTION:Between respective N-channel transistors in a ROM array and the ground, the N-channel transistors 16 are connected in series connection. The gates of the said transistors are connected with the signal line 8 for pre- charging. Accordingly, during a period 14, the transistor 16 are in non-conductive state, and no through current is conducted from the power source to the ground, hence, the output of ROM is stably charged to a H-level. When the period 14 is ended and a signal 8 comes to the H-level, a P-channel transistor 10 turns to be non-conductive, and at the same time, the N-channel transistor 16 comes to be in conductive state. Thus the determination of the output lines 5 of the ROm depends on the presence/nonpresence of the N-channels transistors in the ROM array.

Filed: 1990-02-19
Abstract: PURPOSE:To enable the title etching process to be performed in high reproducibility and practicality while doing the least damage to a substrate after the etching process by a method wherein a reactive gas is activated in an isolated discharge chamber type microwave excitation.ECR plasma chamber while a material to be processed is irradiated with an ion beam or radical beam in the same direction to by dryetched. CONSTITUTION:An etching device for etching II-VI compound semiconductor uses a gas containing highly reactive halogen elements as an etching gas. In order to achieve such a purpose, a specimen preparatory chamber 801 is isolated from an etching chamber 802 by a gate valve 814. Next, the ions produced in an ECR plasma chamber 803 are accelerated by a mesh type leading-out electrode 806 to be applied to a specimen 807. For example, in order to etch away ZnSe 101, a photoresist is used as an etching mask 103; pure chlorine is used as a reactive gas; while the etching process is performed at 100W of microwave incident output, 500V of leading-out voltage, 25 deg.C of specimen temperature with an ion beam in a direction perpendicular to substrate. Through these procedures, the semiconductor layer is hardly damaged by the etching process.

IPC: G06T1/00
Filed: 1983-03-11
Abstract: PURPOSE:To store only a fault signal which is necessary for recognition, to reduce the capacity of a storage circuit, and to shorten the time of the recognition by software by removing a signal corresponding to the permissible position shift of a body to be measured through a removing circuit which is variable in time. CONSTITUTION:The image of the body to be measured is image picked up by the 1st and the 2nd image pickup devices 1 and 2, and the difference signal between video signals from the devices 1 and 2 is obtained by an operation circuit 3 and converted into a binary signal by a binary coding circuit 4. This binary- coded signal is inputted to the removing circuit 10 to remove the vertical and horizontal signal components of the signal corresponding to the permissible position shift of the binary-coded signal. A timing signal generated by a synchronism signal generating circuit 5 is supplied to the devices 1 and 2, storage circuit 6, and a microcomputer 7 which processes information. Then, only the fault signal which is outputted by the circuit 10 and necessary for recognition is stored in the storage circuit, whose storage capacity is thus reduced to shorten the time of the recognition by the software, thereby making a visual decision.
